The study, announced yester day at a news conference held in conjunction with the cancer society's annual meeting here, will involve a thorough analysis of the dea.h records of hun dreds of thousands of workers -.in various industries--including asbestos workers, typographers, printing tradesmen and chemi cal worker'.

Cuyier Hammond, vice president for epidemiology and statistics at the cancer society and,co-ordinator of the occupa tional study, said that press men inhale mists ef carbon black, a close relative of lamp black. whicR is known to be carcinogenic (cancer-pro ducing).Members of New York Typographical Union No. 6, headed by Bertram A. Powers, ' will also" be involved in the study. Men who set type are occupationally exposed- to hot ' metal fuincs and filings, which may contribute to the develop- -i tent of lung cancer, Dr. Ham mond said. The cooperating unions were - selected, in part, for the excel lent health ic-vnis iney nave maintained on their members through tnc years, Dr. Sc-lihoff . -- said. Mr. Powers's union has death records going back to 1K60, the pressmen's union has records sir.ee 1204- and the as bestos workers' union Iras rec ords dating back to its inception i;t 1912. Dr. Seiikoff said that in many cast.-, employers will participate in tho studies. Dr. Hammond estimated the . ..ncer society's contribution to study--which has indeter-- n.inate scone and length--at about Si-million a year. In a speech last night at the society's annual dinner, Elliot L. Richardson, Secretary of Health, . Education and Welfare, said v'.-f. that the.National Cancer In stitute was developing a "Na tional Cancer Plan" under which the (iiOO-miliion in addi tional - cancer funds approved ' by Congress would be allocated.
